- Part Refurbishment: Technicians re-solder broken connections, replace malfunctioning microswitches, or repair harmed transponder coils.
- Shell Replacement: Because the initial housing must be cut open, specialists usually house the fixed circuit board inside a brand-new, pristine plastic shell.
- Testing: Before handing the card back to the consumer, the service technician evaluates the remote frequency and the immobilizer chip on a dedicated testing rig.
